Newbie getting snytax error

Question

I'm trying to create a table with a floating amount of columns, I create the table fine with 3 fixed columns but when I try to add more columns I get a syntax error. Since I'm new to this and learning as I go can anyone point out some errors I'm making.
Thanks
Jim

Using MySql:
stmt = con.createStatement();
      stmt.executeUpdate( "CREATE TABLE TestDataBase1("  +
         "Respondent INTEGER      NOT NULL, "    +
         "Date       VARCHAR (10) NOT NULL, "    +
         "Time       VARCHAR (10) NOT NULL, "    +
         "PRIMARY KEY( Respondent )"                  +
     for( int i = 1; i <= questionText.length; i++ ){
          stmt.executeUpdate ("ALTER TABLE TestDataBase1 ADD COLUMN "+getColumnName(i)+" BLOB NOT NULL");
//.... snip
// return the question that will be the column header
public String getColumnName( int i ){
    return questionText;

Hey, Thanks for the reply.
I was pictureing it like this but I can't envision
your description
|--------|--------|-------|-------|--------------------
|Resp |Date |Time | Q1 |Q2 etc...
| 1 | blah |blah | yes |Male
| 2 | blah |blah | no |Female
| | | | |
||--------|--------|-------|-------|--------------------
|Resp |Date |Time | Q1 |Q2 etc...
| 1 | blah |blah | yes |Male
| 2 | blah |blah | no |Female
| | | | |
|
would become
Respondents table
|--------|--------|-------|-------|--------------------
|Resp |Date |Time | \\\
| 1 | blah |blah |
| 2 | blah |blah |
| | | |
answers table
|--------|--------|-------|-------|--------------------
|Resp | Question | answer
| 1 | 1 | Male
| 1 | 2 | no
| 2 | 1 | Male
| 2 | 2 | yes
This makes it much easier to query results, to get the response to the first 5 questions would be.
select * from answers where question between 1 and 5
under your design it would be UGLY.
This model is easily extended to multiple tests simply by adding a column for the test ID to the respondent table.
